Please mention the source, on the one hand to allow others to have a look at them, too, and on
the other hand just for fairness with regards to the original source/publisher.

hesham, I realize that you did not care to reply to Jemiba's request and I can only agree with him that when posting that amount of high quality company archives. Giving the title of the original company brochure as "your source" is certainly not enough since I'm sure you didn't fly to Germany to compile library volumes...
So even if you don't want (or can't) provide a web link, a mention of the source book you found them is in order! Especially from someone who very often asks for the sources...

Hi! Fw191.
Rearward armaments were very powerful, but no gunner at the tail.

Oh I search "Focke Wolf" not "Focke-Wolf". ;D
I hope to move my post to following topic if my post have some value.

Several thoughts:
- this thread's title is a near duplicate of this one: Various Focke-Wulf projects
- proper spelling of the company name should be Focke-Wulf, including the hyphen, to facilitate forum searches
- this thread, so far, deals only with the Fw 191 - not with other types

It has been pointed out many times before on this forum catch-all-threads titled 'Various/unknown/lesser known -whatever-' do not make for easy retrieval of posted data.

I would suggest 'Focke-Wulf Fw 191' as a new thread title, if this thread is not to be merged with the earlier thread.

Topic renamed and posts from other thread added, thanks for the clue ;)

Wiki abstruct
Design and development
(1)In July 1939, the RLM issued a specification for a high-performance medium bomber (the "Bomber B" program). It was to have a maximum speed of 600 km/h (370 mph) and be able to carry a bomb load of 4,000 kg (8,820 lb) to any part of Britain from bases in France or Norway.
(2)Bomber B bomber was to have a pressurized crew compartment, remotely controlled armament, and was to utilize two of the new 2,500 PS (2,466 hp, 1,839 kW) class of engines then being developed (Jumo 222 or Daimler Benz DB 604).
(3)The Arado Ar E340 was eliminated. The Dornier Do 317 was put on a low-priority development contract; and the Junkers Ju 288 and Focke Wulf Fw 191 were chosen for full development.
(4)An interesting feature was the inclusion of the Multhopp-Klappe, an ingenious form of combined landing flap and dive brake, which was developed by Hans Multhopp.
(5)A crew of four sat in the pressurized cockpit, and a large Plexiglas dome was provided for the navigator; the radio operator could also use this dome to aim the remotely controlled rear guns.
(6)The proposed operational armament consisted of one 20 mm MG 151 cannon in a chin turret, twin 20 mm MG 151 in a remotely controlled dorsal turret, twin 20 mm MG 151 in a remotely controlled ventral turret, a tail turret with one or two machine guns and remotely controlled weapons in the rear of the engine nacelles. However, different combinations were mounted in the prototype aircraft.
(7)Sighting stations were provided above the crew compartment, as well as at the ends of the aforementioned Bola beneath the nose.
(8)The aircraft had an internal bomb bay. In addition, bombs or torpedoes could be carried on external racks between the fuselage and the engine nacelles.
Failure and End of Program
(1)Problems arose almost immediately when the Jumo 222 engines were not ready in time for the first flight tests, so a pair of 1,560 PS (1,539 hp, 1,147 kW) BMW 801A radial engines were fitted. This made the Fw 191 V1 seriously underpowered. Another problem arose with the RLM's insistence that all systems that would normally be hydraulic or mechanically activated should be operated by electric motors.
(2)It is said that the intention to use electric power for almost all of the aircraft's auxiliary systems(fly by wire!!?) (also a fact for the successful Fw 190 fighter), requiring the installation of a large number of electric motors and wiring led to the nickname for the Fw 191 of "Das fliegende Kraftwerk" (the flying powerstation((Same as Boeing787!). This also had the detrimental effect of adding even more weight to the overburdened airframe, plus there was also the danger of a single enemy bullet putting every system out of action if the generator was hit.
(3)Dipl. Ing Melhorn took the Fw 191 V1 on its maiden flight early in 1942, with immediate problems arising from the lower rated engines not providing enough power, as was anticipated.
(4)One surprising problem that was encountered were the Multhopp-Klappe, which presented severe flutter problems when extended, and pointed to the need for a redesign. At this point, only dummy gun installations were fitted and no bomb load was carried. After completing ten test flights, the Fw 191 V1 was joined by the similar V2, but only a total of ten hours of test flight time was logged.
(5)The 2,500 PS (2,466 hp, 1,839 kW) Junkers Jumo 222 engines which would have powered the Fw 191 proved troublesome. In total only three prototype aircraft, V1, V2 & V6, were built. The project was crippled by engine problems and an extensive use of electrical motor-driven systems.
(6)At this point, the RLM allowed the redesign and removal of the electric motors (to be replaced by the standard hydraulics), so the Fw 191 V3, V4 and V5 were abandoned. The Fw 191 V6 was then modified to the new design, and also a pair of specially prepared Jumo 222 engines were fitted that developed 2,200 PS (2,170 hp, 1,618 kW) for takeoff. The first flight of the new Fw 191 took place in December 1942 with Flugkapitän Hans Sander at the controls. Although the V6 flew better, the Jumo 222 were still not producing their design power, and the whole Jumo 222 development prospect was looking bad due to the shortage of special metals for it. The Fw 191 V6 was to have been the production prototype for the Fw 191A series.
(7)Due to the German aviation engine industry having ongoing problems in producing powerplant designs capable of output levels matching or exceeding the 1,500 kW (2,000 PS) figure throughout the entirety of the war years, that had any demonstrable level of combat-ready reliability, the Jumo 222 engines were having a lot of teething problems, and the Daimler Benz DB 604 had already been abandoned, a new proposal was put forth for the Fw 191B series.
(8)The V7 through V12 machines were abandoned in favor of using the Fw 191 V13 to install a pair of Daimler Benz DB 606 or 610 "power system" engines, which were basically coupled pairs of either DB 601 or 605 12-cylinder engines. Their lower power-to-weight ratio, however, from their 1.5 tonne weight apiece for each "power system", meant that the armament and payload would have to be reduced. It had already been decided to delete the engine nacelle gun turrets, and to make the rest manually operated. Five more prototypes were planned with the new engine arrangement, V14 through V18, but none were ever built, possibly from the August 1942 condemnation by Reichsmarschall Hermann Göring of the coupled "power system" DB 606 and 610 powerplants as "welded-together engines", in regards to their being the primary cause of the unending series of powerplant problems in their primary use, as the engines on Heinkel's He 177A Greif, Germany's only production heavy bomber of World War II.
(9)One final attempt was made to save the Fw 191 program, this time the Fw 191C was proposed as a four engined aircraft, using either the 1,340 PS (1,322 hp, 986 kW) Jumo 211F, the 1,350 PS (1,332 hp, 993 kW) DB 601E, the 1,475 PS (1,455 hp, 1,085 kW) DB 605A or similar rated DB 628 engines. Also, the cabin would be unpressurized and the guns manually operated, with a rear step in the bottom of the deepened fuselage — in the manner of the near-ubiquitous Bola gondola used by the majority of German bombers for ventral defense under the nose — being provided for the gunner.
(10)However, at this time, the whole "Bomber B" program had been canceled, due mainly to no engines of the 2,500 PS class being available, which was one of the primary requirements in the "Bomber B" program. Although the Fw 191 will be remembered as a failure, the air frame and overall design eventually proved themselves to be sound; only the underpowered engines and insistence on electric motors to operate all the systems eventually doomed the aircraft. All in all, there were only three Fw 191s ever built (V1, V2 and V6), and no examples of the Fw 191B or C ever advanced past the design stage. The project was eventually scrapped.

Dear Friends,
here I post a model of the Fw 191 (source: War Planes of the Second World War, Green, Vol 9) and a 3-view of the Fw 191C (Source, Die Deutsche Luftrustung 1933 - 1945, Nowarra, Vol. 2).
Regards.
